v BEDSPRING BRACE.

Application filed August 26, 1925. Serial No. 52,555.

This invention relates to improvements in bed spring braces, and particularly to that form in which lateral spring tension is an elemental feature, and the object thereof is to provide. a device by which sagging at the edge is eliminated, while a high degree of resiliency is maintained under all conditions.

A further object is a construction so designed that adjustment thereof may be readily made at any time to suit the require-- ments, or desires of the user.

Other objects and features will be explained in detail in the. following specification and illustrated in the accompanying drawings, in which- Fig. 1 shows atop view of the device mounted in conjunction with the usual form of bed spring certain parts being broken away disclosing certain other lower parts. Fig. 2 shows an enlarged plan view of the principle elements of the invention.

Fig. 3 shows a side view of the parts shown in Figure 2.

Fig. l shows a side view of the main elements under compression.

The invention comprises a plurality of spring tension units of the form illustrated in Figure 2, in which a main link 10 is pivotally secured at one end to the fork members 11 and 12 by a pivot 10, and at the other end to a horizontal rod 13. Pivotally secured in assembly with the said main link 10 and the fork members 11 and 12 is the tension link l l which hasextendiug from its lower extremity the spring 15, which in turn is secured to the frame member 15 by means of the eye bolt 17 The lower ends of the fork members 11 and 12 are pivotally attached to the fiat strips as shown at 18 and 19 which are twisted vertically at the point of attachment as shown at 20. These fiat straps 18 and 19, and the other flat straps 18 are secured to frame 16 in any suitable manner not shown in the drawing, and similarly arranged and aligned are other straps 18 secured to frame 25, and the springs 28, 29 act between the straps of frame 16 and those of frame 25. a vertical standard 21 to which is slidably secured the connecting strip 22, the slot 23 and the nut 24: being provided for the adjustment and locking of same as desired, thus making it possible to raise or lower the said strip at will. The connecting link 30 supports the border frame 25 in movable relation to the horizontal bar 13. The said Secured to the main linklO isv border frame 25 being in rectangular form and connected at the corners by the angle fittings as shown at 26 and 27. Y

The units as above described are mounted at intervals along the frame 16 and secured thereto and to the adjacent flat strips; and in this position co-act with the horizontal "bar 13 and the border frame 25 in the following inanner:

The bar 22 is positioned inwardly from the edge of the spring structure and is'op eratively connected with the lever 10 so. as to actuate the reinforcing spring when weight is applied at a point inward from the edge of the spring structure.

v'hen pressureis applied to the border frame 25 and the strip 22 as would be the case when a person sat thereon, the said pressure is transmitted to the horizontal bar 15 and to the main'link 10 causing the said main link to co-act with the fork assembly, and being pressed downward-and inward exerts a tensional pull on the spring 15. thereby resisting the strain applied and coinpounding the lines of force between the said spring 15 and the springs as shown at 28, 29 etc., and reinforcing the said springs in such a way as to provide ease and comfort while preventing the objectionable sagging tendency. I

As soon as the device is relieved from pressure it returns to its elevated, or normal position and maintains the whole spring structure in even and" symmetrical form.

While adequate and efficient means are herewithshown and described for the accomplishment of the objects as set forth; it is to be understood that the invention is not restricted to the exact detail as shown, but that modification in minor details may be made within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Let-- ters Patent, is as follows:

1. A reinforcing device for the edges of bed springs provided with coiled springs acting between flat straps secured to a frame member and an upper frame member, comprising edge units, each consisting of a forked member pivoted to certain of the fiat straps of the frame member, and extending upwardly and inwardly, a main link pivoted to the upper end of the forked member and extending outwardly, a connecting link pivoted to the outer end of the main link Bin , bar.

and to the upper frame member, a tension link pivotally mounted near the junction of the forked member and the main link, a tension spring connected to the frame member and to the tension link to resist inward movement of the forked member, and a bar situated slightly below the upper frame member inward of the edge and connecting the main links of like units along an edge of the bed spring, the arrangement being such as to resist downward movement of the 2. A reinforcing device for the edges of bed springs provided with coiled springs acting between flat straps secured to a frame member and an upper frame member, com prising edge units, each consisting of a forked member pivoted to certain of the flat straps of the fame member, a main link pivoted atone end to the upper end of the forked member, a con ecting link pivoted to the other end of the main link and to the upper frame member, a tension link pivotally mounted near the junction of the forked member and the main link, a tension spring connected to the frame member and to the tension link to resist downward movement of the forked member, and a bar situated slightly beloW the upper frame member inward of the edge and connecting the main links of like units along an edge of the bed spring, the arrangement being such as to resist downward movement of the bar.
